That's a good point you bring up Mike. I poured some of the coffee into a cup of sugar to mix. I then placed the pot back on the stove and allowed for the coffee to fill up the top compartment. Although I let the top fill up with coffee, I wondered if I was burning any of the grounds during this period of time because I was more focused on mixing the sugar and coffee, which took a couple of minutes for me. Should I just remove it from the burner and allow for the coffee to continue to fill up the top, or lower the heat?
